Ok I am moving in about a week and I am looking to build new boxes for my 12 inch vega drivers. problem I dont have any idea where to go with a design. I dont know any specs on the sub so if any one could help me out with an idea where to start?

If I were you I'd figure out what type of enclsoure they were originally used in and make something of a copy using a similar alignment. Typically manufactures put their own drivers in suitable enclosures for their product. Why are you creating new boxes may I ask?
